If you have tried searching for the popular Anker battery packs for your smartphones or tablets, you may have become confused by the PowerCore PD, II, PowerCore+, Powercore, and Astro series of products. The PowerCore PD, PowerCore II, PowerCore+, PowerCore, and Astro battery banks are available in the stores at the same time, often look the same, have same capacity, and sometimes even have same or similar prices!

Also many shady sellers sell old Anker products on Amazon and other sites under false claims of being the “latest”.

To further complicate matters, all the five – PowerCore PD/II, Powercore+, PowerCore Lite, Powercore, and Astro – are available in the Amazon marketplace side-by-side. The “second” or “third generation” of Astro portable power banks are even wrongly shown in Amazon product listings as the more recent versions!

Even Anker itself continues to sell old and new versions of the powerbanks at the same time with EXACTLY same name and unless you know what you are looking for, you may well end up buying an older version powerbank at same price as the latest one!

Let us simplify the situation for you –

#1 Anker PowerCore USB-C PD Series are the latest Anker powerbanks released in 2021 to 2018. All PowerCore USB-C PD Series power banks support USB-C PD and can hence fast charge latest iPhones 12/11/XR etc.. They also get charged fastest compared to all older PowerCore or Astro models.

#2 Anker PowerCore II Series Anker power banks were released in 2018. All PowerCore II Series power banks fast-charge Samsung phones including latest S21, S20 to S8 as they support Quickcharge 2.0. The also get charged twice as fast as old PowerCore or Astro power banks.

#3 Anker PowerCore+ power banks are BETTER and NEWER than Astro Gen 1 or Gen 2 of same capacity.

#4 An Anker PowerCore (without the +) power bank is BETTER and NEWER than Astro Gen 1 or Gen 2 of same capacity.

#5 Anker PowerCore+  and Anker PowerCore power banks exist side by side with PowerCore+ usually having some extra features with PowerCore offering excellent value for money.

Anker product timeline goes on like this when considering powerbanks of equivalent or nearly similar capacity.

(Oldest & outdated)
Astro 2nd  gen or Astro 2
(Old and not recommended)
PowerCore Series
(Obsolete, No USB-C, OK value for money) 
PowerCore+ Series (2015-2016)
(Obsolete, No USB-C)

PowerCore II Series (2017/2018)
(2017-2018, No USB-C, Fast charging for Samsung/Androids)

PowerCore PD Series (2021, 2020, 2019, 2018)
(2021-2018, Latest USB-C fast charging for iPhone 12/11/XR etc. and latest Samsungs/Androids)

Anker PowerCore vs Astro

When comparing Anker’s PowerCore or PowerCore+ products with Astro series of battery banks, the features and battery capacity significantly increase from Astro to PowerCore for the same approx. battery capacity. For example, while old Astro 2 Mini 3200 lipstick sized power bank had 3200 Mah Capacity, the newer PowerCore+ 3350 Mini of exactly same size and design has 3350 MaH capacity. This is possible as the newer PowerCore+ 3350 Mini  has a more advanced Li-ion battery inside.

The difference and better performance also continues in other aspects. For example, Astro 2 3200 mini has a charging current capacity of 0.8 A while PowerCore+ Mini 3350 battery packs get charged faster with a 1.0 A charging current.

Moreover, as the charging circuits are upgraded with successive generations many advanced charging and security features have been introduced in the later latest PowerCore PD PowerCore, PowerCore+ and PowerCore II Series power banks that lead to long battery life, reduced overheating, better efficiency, and better protection of the powerbank circuits etc.

We recommend avoiding Astro series products altogether as newer PowerCore PD, II/PowerCore+ portable USB chargers offer lighter weight, more features and more value for money.

Do you Need USB-C PD or Quickcharge 3.0?

USB-C PD power banks is the latest technology trend in power banks as all latest iPhones (11, 11 Pro/Max, XR/Xs to 8/8+) support zero to 50% charging in 30 minutes with USB-C PD. All latest Android power banks also support USB-C PD fast-charging. Also, USB-C PD power banks will get charged in less than half the time taken by regular power banks. For iPhones or Samsung phones, you do not need Quickcharge 3.0/2.0 and USB-C PD power banks such as PowerCore Slim 10000 PD, Anker PowerCore Essential 20000 PD or Anker PowerCore+ 26800 PD are better option. 

Here are the points to consider:

  • If you own iPhone 12, 11 series,  XR, XS, XS Max, 8, 8+, X,  or if you want to be absolutely future proof and do not mind paying extra, buy a 18 watt+ USB-C PD powerbank such as PowerCore Slim 10000 PD, Anker PowerCore Essential 20000 PD or Anker PowerCore+ 26800 PD are the best choice currently for fast charging latest and upcoming smartphones (both Apple iPhones 8/8+/Xand Samsung Salaxy S9/S8/Note 8 as well as other Androids.
  • Future Proofing:  As of now, 18-watt fast charging over USB-C PD is the latest trend for power banks. Both Google Android and Apple are supporting it in their latest phones. Therefore, buying a 18-watt PD fast charging power bank such as PowerCore Slim 10000 PD or  PowerCore Essential 20000 PD that will serve you perfectly well in the future for all iPhone and Android smartphone fast charging needs.
  • If you plan to use your Powerbank for charging Samsung Galaxy S10 S9, S8, S7, S6, Note 8, Note 5, Note 4, J series, A series phones or any iPhones  then you DO NOT require QuickCharge power banks. All latest Samsung phones support USB-C PD charging. iPhones do not support Quickcharge at all.
  • If you already own a LG/Xiaomi phone that supports Quickcharge 3.0 or plan to own such as phone, then a powerbank with Quickcharge 3.0 Output is a good investment as it will charge your phone to 80% in 30 minutes when you are in a hurry. Here is a comprehensive list of all smartphones with QuickCharge 3.0 support.

PowerCore PD, PowerCore II & PowerCore+ offer the most advanced features
PowerCore offers best value for money deal

In the end, when it comes to Anker Powercore vs Astro, the easy conclusion is to buy the latest PowerCore PD series power banks for best performance compared to any Astro series power banks of equivalent capacity. For example, say if you are looking for a powerbank around 10,000 mah, then PowerCore Slim 10000 PD is newer and better than the older Powercore+ 10050 with QC 2.0, older PowerCore 10000, or the even older Astro E3 10000.  This is because PowerCore Slim 10000 PD supports fast charging for latest iPhones including 11/11 Pro and the latest Samsung Galaxy smartphones such as S10, S9, S8, S7 etc and also gets charged in 4-5 hours using iPhone 11 Pro/Max chargers or Samsung/LG/Moto/Pixel chargers.

Unfortunately for customers, probably due to the continued popularity and familiarity of the Astro brand, Anker has not discontinued the Astro series powerbanks. At the same time, it has introduced multiple generations of Powercore+ series battery packs at quite similar size, price and designs as the Astro series, creating a confusing mix of the three brands.

Here is a comprehensive list of Anker External Battery Packs according to their battery capacity. We have also included the Amazon shopping links of the only authorized Anker products seller on Amazon – AnkerDirect.

    1. Hi Larry,
      No, Powercore II 6700 will not charge Samsung Note 9 at its fastest possible charging speed. Powercore II 6700 provides maximum 2 amp charging current (5v @ 2amp) to Note 9 and will charge Note 9 from zero to 50% in about 1 hour.
      For about $10 more, you will get PowerCore II Slim 10000 with 50% more battery capacity and support for fast-charge for Note 9 and also get fast charged itself in 5 hrs (faster than PC II 6700!)


  1. Hey I need some advice. I cant decide which Powerbank I should get. There are 2 types that I like.

    1) Powercore+ 20100 USB C
    2) Astro E7

    I have a Huawai P10 which has USB C charger and I am looking for a powerbank that charges very fast. Which one should I get?

    1. Hi Julia,

      Thanks for the query. Unfortunately, for Huawei P10, none of these powerbanks will support its maximum charging speed as P10 uses proprietary “FastCharge” & “SuperCharge” technologies (9v at 2 amp & 4.5v at 5 amp) that are incompatible with these two powerbanks.

      The only powerbank in the market (that we know of) which supports the maximum charging speed (4.5V at 5 amp) of Huawei P10 is Huawei’s own (Amazon Germany link) Huawei Honor AP08Q powerbank. (Amazon UK LINK). The AP08Q is a great powerbank but is not always available online.

      However, the good news is that you can use any good USB PD type USB-C powerbank such as Anker PowerCore 26800 USB PD or RAVPower 20100 USB Hubs PD to charge the Huawei P10 at its “second fastest” (9volt at 2 amp) fast charging speed! 🙂


  2. Hi there,
    I have a question and don’t get the thing by heart. What is your opinion on these ones?

    PowerCore+ 3350 Mini
    PowerCore 5000mAh
    Astro E1 5200mAh
    Astro 2nd Generation 6000 mAh

    The last one is my least favorite. I kind of like the second.

    Thank you very much on helping!

    1. Hi Niclas! 🙂

      As they all are priced about the same-

      PowerCore 3350+ Mini is easily the best choice among the 4 powerbanks mentioned by you. It is real tiny in size/weight and excellent as a single full charge (0-100%)or two top-up charges powerbank.

      If weight is not a concern, our recommendation in this price category is RAVPower 6700 mAh It is the lowest priced powerbank and has 2 fast charging ports including 1 2.4 Amp port with weight of 7.1 oz;

      The other three powerbanks mentioned by you (PowerCore 5000mAh, Astro E1 5200mAh & Astro 2nd Generation 6000 mAh) are 2-3 year old versions and are quite bulky for the capacity/price offered. And for just few bucks more you can get the plain vanilla 6.6 oz Anker PowerCore 10000 (available currently at a pretty discount on Amazon) that offers double the charge capacity of these powerbanks.

  3. I’ve lost count of how many Anker products I now own. The charging efficiency difference is notable. Thanks for speeding up my life!
